Keep Laser-Cut Work Cool and Enjoy Numerous Benefits

TRUMPF Inc., Farmington, CT, introduces CoolLine, a new option for its 2D laser-cutting machines. During laser cutting, the CoolLine nozzle directs a water mist around the laser beam as it reaches the workpiece. In doing so, CoolLine reduces the heat transferred in the immediate cutting zone and allows fabricators to achieve contours that would otherwise be difficult or impossible to process.

With this new option, users can cut small sidewalls and difficult geometries more efficiently, especially in thick material. Fabricators also will, say company officials, enjoy a considerable increase in process reliability when laser processing low-grade material or material of varying composition.

CoolLine is fully integrated into the cutting process via a specially designed laser-cutting head, various nozzles and a water supply tank. With CoolLine, fabricators will enjoy higher-quality cuts with smaller contours or greater complexity, for increased flexibility. The option also allows fabricators to nest parts more closely together.
